:A compatibility layer for the PlayStation 4. It's currently unable to boot any commercial games. For more information, visit the devs There's a [https://discord.gg/yVbPkmc Discord server]. The server itself is not very active to the public because discuss in, however most talk is being done in private between the developers.

:RPCS4 is a private project being worked on by one of the original developers of [[RPCS3]], DH. Work is being done in private, so there is little public information about it. Accordingly to DH, it currently runs on unix-like OS, and is able to run PS4 games (without graphics) and display errors. <ref>https://www.reddit.com/r/pcgaming/comments/cxx5h3/we_are_team_rpcs3_the_playstation_3_emulator_we/eyoqzes/</ref> The Github page hasn't been updated and appears to only be there as a placeholder until an actual release(if ever releases).

Due to the PS4's x86 architecture and FreeBSD-based operating system, emulators for the device will by and large be very unconventional. Despite the x86's instruction set being '''huge'''<ref>{{cite web | url= https://en.wikipedia.org/wiki/x86_instruction_listings | title= x86 instruction listings | Wikipedia}}</ref>, a trait that would typically lead to years of development time by emulators, it opens the ability for pre-existing hypervisors to do the heavy lifting, eliminating the need for a recompiler. There is also, as of writing this, little to no documentation on the GPU (a modified Radeon 7970M with disabled stream processors) used in the PS4's APU, and it will require a complete re-implementation by emulator developers. End-users may wish to preform a preliminary dump of the required files from their PS4 using the [https://phi.nz/orbital/tools/dumper/ Orbital Dumper]. ===PCSX4 & Fake Emulators===Because most people don't understand how emulation really works, people try and take advantage by making [[Emulator scams|their own fake emulator]] for malicious purposes. The PS4 has been the subject of a lot of these scams mainly since it was the "newest" console at the time, the most notable one however was one called '''PCSX4'''. It's a really clever cover up, the name is similar to "PCSX" and "PCSX2" (both of which are well-known PlayStation emulators) and has a nice looking website similar to other recent emulation projects with the same elements. What makes it worse is it's one of the first results on Google when searching for "PS4 emulator". If there was really an emulator this early that could play PS4 games in 4K resolution at 60 FPS with little to no issues it would have made a ''huge'' deal. It's also important to remember that the PS4 supports remote play for PC and mobile so it's ''very'' easy to fake a recording and claim it's an "emulator" running it.
